Adding Cells to Dynamic UITableView DataSource | Swift - swift

Question

I have a dynamic UITableViewDataSource that takes in a Model and a UITableViewCell
I would like to insert a different UITableViewCell into the 'nth' (10th for example) row... (for Google Ads)
DATASOURCE
class ModelTableViewDataSource<Model, Cell: UITableViewCell>: NSObject, UITableViewDataSource {
typealias CellConfigurator = (Model, Cell) -> Void
var models: [Model]
private let reuseIdentifier: String
private let cellConfigurator: CellConfigurator
init(models: [Model], reuseIdentifier: String, cellConfigurator: #escaping CellConfigurator) {
self.models = models
self.reuseIdentifier = reuseIdentifier
self.cellConfigurator = cellConfigurator
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return models.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let model = models[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: reuseIdentifier) as! Cell
cellConfigurator(model, cell)
return cell
}
}
I then add an extension for each Model
MODEL
extension ModelTableViewDataSource where Model == SomeModel, Cell == SomeCell {
static func make(for someModel: [SomeModel], reuseIdentifier: String = "Identifier") -> ModelTableViewDataSource {
return ModelTableViewDataSource(models: someModel, reuseIdentifier: reuseIdentifier) { (someModel, someCell) in
someCell.model = someModel
}
}
}
What is the best way to implement this keeping the re-usable functionality of the UITableViewDataSource

Answer 1

I thought of this:
create a subclass
override numberOfRowsInSection to return number of rows + 1
override cellForRowAt to handle the 10th row
class ModelTableViewDataSourceWithAd: ModelTableViewDataSource {
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return super.tableView(tableView, numberOfRowsInSection:section) + 1
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if (indexPath.row == 9) {
// return Google ad cell
} else {
return super.tableView(tableView, cellForRowAt:indexPath)
}
}
}
and then the creator:
extension ModelTableViewDataSource where Model == SomeModel, Cell == SomeCell {
// ...
static func makeWithAd(for someModel: [SomeModel], reuseIdentifier: String = "Identifier") -> ModelTableViewDataSource {
return ModelTableViewDataSourceWithAd(models: someModel, reuseIdentifier: reuseIdentifier) { (someModel, someCell) in
someCell.model = someModel
}
}
}
